The sum of one–half a number and two-thirds the number is equal to twenty-five less than twice the number.

Answer: \frac{1}{2}x + \frac{2}{3}x = 2x - 25

Step-by-step explanation:

First, let's analyze the phrase "the sum of one-half and two-thirds the number". This would translate to:

\frac{1}{2}x + \frac{2}{3}x

Then it says the last part of the expression is "twenty five less than twice the number"

2x - 25

Then, equal the two parts of the equation to each other.

\frac{1}{2}x + \frac{2}{3}x = 2x - 25

Hope this helps! :)

<u>Given</u><u>:</u><u>-</u>

  • f(x) = x²

<u>Evaluation</u><u>:</u><u>-</u>

e).

==> f(x) = x²

So,

==> f(3x) = (3x)² = 9x²

f).

==> f(x/2) = (x/2)² = x²/4

g).

==> 3f(x) = 3x²

h).

==> 2f(x-1)+5 = 2(x-1)²+5 = 2(x² + 1 - 2x ) + 5

= 5x² + 5 - 10x + 5

= 5x² - 10x + 10

Somebody help me please? im timed!

We know that

Domain:

It is all possible values of x for which any function is defined

we are given function

f(x)=-(x+3)(x-1)

we can see that our function goes from left to right side

so, domain will be all real numbers

Range:

Range is all possible values of y

we can see that

largest y-value is 4

smallest y-value is -inf ...because it keeps going downward

so, range is

(-\infty , 4]

so, option-C...........Answer

Please can you help I’m so stuck

So as far as my knowledge goes, your answer for (a) is right - it is a cylinder.

(b) is a triangular pyramid - this is because the base is a triangle ( aka the one in the middle) and there are three triangles surrounding it and when they come together, they form a triangular pyramid.

hope it helped, if it did, please make me the brainliest answer - I need to move on to the next level :)

A car dealer recently sold five cars for the following profits: $10,126, $9,999, $12,398, $12,007, and $4,567. What was the mean
yawa3891 [41]
The mean is the average
to find the average, first you add all the numbers together
10,126 + 9 999 + 12,398 + 12,007 + 4,567= 49,097
since you added five numbers together, you will divide by five
49,097 ÷ 5 = 9,189.40, so the answer is B
